Turbocad's finally selling mods :)

I took a few video's to show you guys the vapor polishing in action. each piece takes multiple dips into the chamber with a bit of flash off time in-between dips.

here is a video of a door going through the process without all of the pauses for flash off time edited out of it yet.

I'm going to edit up a better video showing full bodies and faceplates and black ultem polishing too, but for now this should give you a good idea of how it works

the ultem can't stay in the chamber longer than 3 or 4 seconds at a time or it will build up too much vapor condensation on it's surface and start to make drips or runs, in a lot of ways it's kinda like spraying on a clear coat in that you need to spray many light coats and build up the clear coat evenly, here is the same, many small dips to build up the polishing out to an even full glass finish.

Lotsa work buddy, how's the gas recovery working out with the new setup?

 

[turbocad6]

not so good, still loosing a lot of volume to dissipation. I def gotta come up with some sort of ventilation system for down here and enclose this operation, these are some nasty gasses that really shouldn't be breathed at all

 

[Irish Messing]

I was kind of wondering when I saw you taking a few rips in the video... Stay safe!

Acetone?

 

[turbocad6]

not acetone, this stuff makes acetone seem pretty mild in comparison, it's a miscible mixture of 3 very nasty chemicals, it's very volatile and noxious, but it's not combustable like acetone at least

 

[Alexander Mundy]

That is totally awesome!
Kudos for figuring out the process.

Now figure out a way to automate that in an enclosed ventilated chamber.

 

[turbocad6]

you and I think alike I already ordered a few belt pulleys and a mechanical chain link conveyor belt. going to try to rig up a carousel so I can hang like 10 mods worth of parts in an enclosure and then have it be able to rotate though them automatically kinda like a dry cleaners conveyor. I need to figure out a way for it to stop each mod part over the tank then dip each one for a set amount of seconds, then retract and move on to the next, ideally all cnc controlled. I'm looking into using either arduino, pibot or a tinyG controller for it, only problem is I don't know the first thing about programming any of those so it may wind up being only semi automatic at first until I can learn how to program a simple circuit like this. I already built it in my head but that's only half the battle

past few months I've been having a few dizzy spells off and on, lasts a few days and I get really dizzy whenever I get up or lay down too fast, kinda like vertigo I guess from my google searching on the subject... I haven't really associated it with these vapor polishing sessions at first but now I'm starting to realize that they may actually be related as the past few days it's been happening again and of course I just did a few more sessions of this polishing... I don't really want to kill myself building these things so I def need to control the fumes here

 

[rudy4653]

Gotta get these mods polished!!!

 

[penguiness]

rudy is right. Get you a good mask until you can come up with another solution!

 

[turbocad6]

I do have a good mask that I use when I'm working on cutting and sanding some of the exotic woods, that stuff can be pretty irritating to the lungs too but most masks are more for particulate filtration than actual vapor, the only kind of mask that will do well here is a full on gas mask or a fresh air feed system.

I ordered a few of these:

and one of these:

to start to build a vapor dipping carousel conveyor type setup running it round with a stepper motor and even making the individual hanger drops that can dip and retract each hook aren't really going to be the most challenging part, it's the whole control logic to fully automate it that's gonna trip me up. wish I could find someone who vapes and also who knows how to program a micro controller, I can see a little bartering action going on I really would like to have at least something in place by the time I need to dip the next batch, even if it's a semi manual setup at first but so it can at least be enclosed and vented. standing over this thing open like this for hours at a time dipping these things by hand is just not so much fun, especially if it's poisoning me each time I do it. the last session winded up completely evaporating 100ml of these chemicals in a matter of a few hours. I do actually have a copper coil of chilled antifreeze coolant that is circulated through it at the top of my tank to try to keep the vapors from escaping by keeping a cooler dense blanket of cold air at the top of the tank to avoid vapor escape but it doesn't fully contain it apparently

one of the 3 key ingredients of my dipping vapor formula is methylene chloride which by itself produces Phosgene gasses when it is decomposed by boiling down to gas-off like this. Phosgene is such a nasty chemical that it has actually been used in the past as a chemical warfare agent, deadly stuff right there. I don't think that the ppm I'm exposing myself to is anywhere near being deadly of course or I wouldn't be doing it, but then again I don't really know how this works in conjunction with the other 2 chemicals t's combined with and I guess it's not so pleasant either even at these lower concentrations, so...

but most masks are more for particulate filtration than actual vapor, the only kind of mask that will do well here is a full on gas mask or a fresh air feed system.

Lots of respirator options. Local Paint&Body supply shop probably have something that would work.

Just activated charcoal would probably be enough, but you'd need to check each of the items in use.

 

[turbocad6]

the respirator I have is probably ok for this really, it's a 3m charcoal thing with a big battery pack that hangs off your belt to run a fan that's built into the mask. it's a full face mask that looks very much like the typical gas mask and it's designed for haz mat use with double filtration. the fan is cool because the face shield never fogs up or gets stuffy in there, it sucks filtered air right into the mask for you, but the problem with that is this polishing thing is an all day affair spread over a couple of days, the chamber can run for hours at a time. putting that mask on for 15-20 minutes at a time when sanding or cutting a bit of wood isn't so bad but no way I'm wearing that mask all day, I def have to enclose it

this vapor is like argon in the way that it is heavier than air and it sinks, so whatever does escape really winds up pooling and collecting down low in the room around floor level, so really my exposure has to be relatively low I think but better safe than sorry

I really want you to be safe! No mod in the world is worth risking your health for!

 

[rudy4653]

Sounds like you need to take a vapor polishing break after this batch and work on black ultem & delrin batch.

 

[muzichead]

It would seem every time you add a process to your devices, its like reinventing the wheel all over again!! You do have a great looking device though...

So.. completely different subject...
Don't know about anyone else here that has the new silicone cappy bottles but I found a bit difficult/messy to refill. If I leave the tubing connected to the 510 it's hard to just screw off the top and remove the bottle when in the mod , then if I take the whole bottle and tube out and fill when I put the cap back on it leaks out the top of the tube due to inside pressure and need to wipe clean before reinserting. So, I found this 30 ml refill bottle system made by the same people that put out the original Italian soft bottles. Ordered one to try out. You unscrew the atty, screw this in, and squeeze to refill bottle.Yes it's a bit of a pain to have to take off the atty every time but seems like it would be clean and no mess. Also no need to constantly take out bottle or remove tubing from the mod. I'll let you know how it works.

 

[Train2]

Actually, I think I read that the easy way is to
- take off the atty
- squeeze out the in-place bottle - get all the air out and HOLD
- screw on the full filler-bottle
-Release the squeezed empty - and it will SUCK IN the juice from the filler.

Otherwise, you'd be creating pressure trying to push juice into a bottle full of air...

Hope it works well!
I agree - opening and refilling these is a bit difficult...

Yes you are right, I watched the you tube video before I bought. I was too lazy to describe in detail.

I've got one of those and have another two coming. I got them with these mods in mind as I was running into the same issue. I'm looking forward to trying it out for myself [emoji3]

Well, it's not real useful if you won't wear it.

As long as the vapor doesn't bother your skin, the half mask design is a lot more comfortable. Maybe add some goggles if it bothers your eyes.

I think the real concern is inhalation more that skin or eyes. You could probably tell right off if the latter were an issue.

You have a long term plan. Just thinking about short term while you work out the details/bugs.
